PP Filament by purefil – Lightweight, Flexible & Chemically Resistant

Polypropylene (PP) is a semi-crystalline thermoplastic and one of the most widely used plastics worldwide. Known for its low density, excellent chemical resistance, and flexibility, PP is an ideal material for functional 3D prints requiring durability and lightweight properties.

Why is PP Filament a Smart Choice?

purefil’s PP filament is made from a specialized polypropylene with lower crystallinity, resulting in better transparency and reduced warping during printing. Its lightweight nature allows you to produce more parts per spool compared to other materials. PP is also known for:

• Superior chemical resistance – Highly resistant to acids and bases, making it perfect for lab and industrial applications.
• Durability & flexibility – Ideal for creating living hinges, snap-fit parts, and functional prototypes.
• Food-safe & dishwasher-proof – Meets EU Regulation No. 10/2011 for food contact materials.
• Stress crack resistance – Outperforms polyethylene (PE) in long-term durability.
• Exceptionally low density – Print lightweight and durable parts with minimal material consumption.

Key Features of PP Filament:

• Low density – More parts per spool with lightweight strength.
• Great flexibility & fatigue resistance – Perfect for living hinges and snap-fit designs.
• Excellent chemical resistance – Withstands acids, bases, and solvents.
• Food-safe & dishwasher-proof – Ideal for food-grade applications.
• Poor cold resistance – Becomes brittle at sub-zero temperatures.

PP filament is an excellent choice for engineering projects, medical applications, packaging prototypes, and industrial parts where flexibility and chemical resistance are key.
